The function vpfn_pages() can help us determine the number of vpfn nodes on the vpfn rb tree within a specified range. This allows us to avoid searching for each vpfn individually in the function vfio_unpin_pages_remote(). This patch batches the vfio_find_vpfn() calls in function vfio_unpin_pages_remote().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
